Renowned French consumer magazine Que Choisir has issued a stark warning through its blacklist of problematic cosmetics.
It flags beauty and hygiene products containing health-hazardous ingredients. Remarkably, 400 products include these risky components.
Some stand out as especially concerning, combining multiple dangerous substances or targeting vulnerable groups like pregnant women, babies, and children.
Despite assumptions that manufacturers protect these populations, evidence shows otherwise. Here's what to watch for:

Many products for babies and children still contain MIT (methylisothiazolinone), a potent allergen dubbed "Allergen of the Year 2013."
Additionally, endocrine disruptors appear in items aimed at sensitive users, available in supermarkets and pharmacies.
Here are the 10 products with toxic ingredients to avoid:

This ultra-smoothing spray for kids includes ethylhexyl methoxycinnamate, cyclopentasiloxane, and BHT—three recognized endocrine disruptors.
Labels like "paraben-free" or "with organic sweet almond" can mislead; always check ingredients thoroughly.

Que Choisir highlights Avène cold cream, commonly used on babies' and children's skin. It contains an endocrine disruptor and phenoxyethanol, deemed toxic for young children by France's National Medicines Safety Agency.

Dexeryl cream features propylparaben. Pierre Fabre Laboratories classify it as a medicine for specific dry skin conditions like atopic dermatitis, not general use.
They note: "Apart from these authorized medical indications, the use of the drug is not recommended, since the laboratory, having not carried out clinical studies, cannot guarantee either the efficacy or the safety of the drug."
For baby's skin, consider a homemade liniment using a simple recipe instead.

Pregnant women should skip Elancyl's stretch mark prevention cream due to cyclopentasiloxane, not advised during pregnancy. Opt for a natural stretch mark treatment alternative.

This teen-targeted anti-pimple gel packs two endocrine disruptors and two allergens (MIT and MICT)—a risky mix. For acne, try these 11 effective natural recipes.

Even premium pharmacy brands like Klorane falter: their soap-free nourishing shower gel contains endocrine disruptors.

This hair treatment promises shine and repair but delivers two allergens (MIT and MICT) plus two endocrine disruptors.

Yves Rocher's sun spray includes four endocrine disruptors. For family-safe options, make this homemade natural sun protection.

These wipes contain sodium lauryl sulfate, a known irritant—not ideal for intimate hygiene.

Hair dyes often include allergens like MIT, MICT, and p-phenylenediamine. While legal in rinse-off products, prolonged exposure during application raises concerns.
